Bug ID: 53123
           Summary: ListView: Ctrl+Shift+LMouse multiselect on
                    LVS_OWNERDATA listviews erroneously sends
                    LVN_ODSTATECHANGED
           Product: Wine
           Version: 7.10

Example file that highlights the bug by crashing.
As in the title: ListViews that do not have LVS_OWNERDATA set as style falsely
do send an LVN_ODSTATECHANGED notification.
This notification is ONLY for LVS_OWNERDATA style ListViews and should not be
sent otherwise.
Steps to reproduce:
1. Run the attached `print-notify.exe`
2. Select a row by clicking on it
3. Hold down CTRL+SHIFT and select another row by clicking with the left mouse
button (selecting multiple rows)
The attached application crashes when using wine. Windows 7 does not.
This bug can only be triggered by left mouse clicks.
A patch is available as part of my `Fix LVS_OWNERDATA list view multi select.`
patch set. This report is solely to prove the bugs existence and increase the
likelihood of the patches getting accepted.
